In winegrowing, Mass selection (or Sélection Massale in French) is a traditional method of propagating grapevines. Instead of using clones (which are genetically identical plants selected for specific traits), mass selection involves choosing the best-performing vines from an existing vineyard and using cuttings from those vines to plant a new vineyard or to replant missing vines.

Here's how it works:

- Farmers observe their vineyard over several years.

- They mark individual vines that show desirable traits — like better fruit quality, disease resistance, yield balance, or adaptability to the local conditions.

- In winter, they take cuttings from these selected vines.

- These cuttings are grafted onto rootstocks and grown into new plants.

**Why use mass selection?**

- It preserves genetic diversity within a vineyard (unlike clonal selection, which reduces it).

- It helps maintain traditional vineyard character and complexity, important for terroir expression.

- It adapts better to local soils, climates, and evolving challenges like disease pressure.

**Downsides?**

- It's slower and riskier compared to buying certified clones.

- Results can be inconsistent because you're not guaranteed uniformity.

**Short version:**

Mass selection is like *handpicking the best individuals to continue a family line* rather than cloning one perfect member.
